Musashi Bulk Extreme is a high-calorie mass gainer designed to support those in a dedicated bulking phase, particularly hard gainers and growing adolescents. When building muscle and increasing size, eating enough clean, nutrient-rich calories is essential—and Bulk Extreme delivers the macros you need to reach your goals.

This scientifically formulated blend features a combination of whey protein isolate, whey protein concentrate, whole and skim milk powder, and added MCTs. It’s tailored to help you meet your daily protein, carbohydrate, and calorie needs in a convenient and effective way.

Benefits of Musashi Bulk Extreme:

  • High in protein and carbohydrates for serious mass gain
  • Supports bulking with 376 calories per serve
  • Includes MCTs for sustained energy and lean mass support
  • Naturally occurring amino acids to aid muscle recovery
  • Ideal for hard gainers and adolescent growth phases

How many calories are in each serve?
Each serve contains 376 calories, making it an efficient way to boost your intake during a bulking phase without relying on extra meals.

Who should use Bulk Extreme?
It’s ideal for hard gainers, active adolescents, or anyone in a calorie-surplus phase focused on building lean muscle and size.

Bulk Extreme makes it easier to stay on top of your macronutrient targets while supporting strength and muscle growth. Power your bulk with a formula that works as hard as you do.

Mix 90g (approx. 2 ½ scoops) of Musashi Bulk Extreme with 500ml of cold water or milk. Shake or blend until fully dissolved. Consume immediately after training or between meals to increase calorie and nutrient intake. Use 1–2 serves daily depending on your bulking goals and dietary needs.
